Some changes have no effect.

I've just created a new forum. http://ranadiktuz.darkbb.com

When i try to customize it, some changes have no effect after saving.
When I try to change Configuration, Forum width, then save, it says something like "updated successfully" but the problem is, after viewing the forum, nothing's changed. Width is still the same. No matter what value i put in %, either 50%, 90%, 98%, nothing happens after saving. Forum width doesnt update. Same with portal width.

Also, about forum widgets. Even if I enable the display of the forum widgets, widgets doesnt display. Left and right widgets wont display.

How do I fix this?

I even try to change my other forum's width, different address, still, it doesnt work. So, this is not specific to my new forum account but in general, i guess. Coz I have the same problem with my other forumotion account.

same here. i cant change the font colours.

This maybe a feature of the template you are using.
You could try some different templates to see if that is what the problem is.

still it doesnt work. even display forum widgets doesnt work.

i dont think this is a template error. changing template still have no effect.

problem solved.
